Kestrel 4300 handheld anemometer

Kestrel 4300 is a handheld anemometer specifically designed for the construction industry, capable of measuring and displaying evaporation rates and other environmental parameters. Users only need to input concrete temperature data (measured through IR or temperature probes), and the instrument can immediately calculate and display the evaporation rate. The evaporation rate is jointly affected by relative humidity, temperature, and wind speed. Evaporation rate is an important environmental indicator, which is specifically used to ensure that they avoid plastic shrinkage cracks in expensive concrete facilities. When plastic shrinkage cracks occur, the surface concrete dries up too quickly and has sufficient time to crack before shrinkage.
Previously, construction foremen had used Kestrel measurements to measure the situation, and then referred to the American Concrete Institute chart to calculate the evaporation rate. The new Kestrel4300 construction weather tracking is working for them! Users can simply enter the concrete temperature (using infrared or probe thermometers) and calculate the instantaneous evaporation rate at 4300. In addition to evaporation rate, Kestrel4300， Still a sturdy and durable weather tool for all construction purposes, measuring and recording the following weather conditions to accurately operate these workers and equipment.
Kestre's mini tripod is an excellent companion, measuring 15 inches tall and positioning concrete over 20 inches. Each Kestrel is individually calibrated, NIST traceable standard, and comes with a free certificate of conformity. Individual NIST certificates can also be adjusted for use.
Kestrel4300 is a rotating cup anemometer with a compact size and easy portability. Using high-precision bearings and lightweight impellers, it can accurately measure wind speed values, even in very low wind speeds (as low as 0.3m/s). If the impeller is damaged, it can be replaced.
Kestrel 4300 can also calculate the wind chill index, heat index, dew point temperature, wet bulb temperature, evaporation rate, and density height based on measurement data from various sensors. Wind chill is a human perception of wind speed and low temperature. The higher the wind speed, the lower the perceived temperature; The heat index is a human perception of temperature and relative humidity. The higher the relative humidity, the higher the perceived temperature; Dew point temperature refers to the temperature at which air cools to saturation without changing the water vapor content and air pressure; Density altitude is the height obtained by verifying the pressure altitude value against temperature.
The Kestrel 4300 is powered by 2 AAA batteries, which are replaceable and have 2 power-saving modes to extend battery life. Available languages: English, French, Italian, Spanish, and German.
